CATSUP-CAP.

Application filed July 26, 1919.

T 0 all whom it may concern Be it known that I, CHARLES I'IAMMER, a citizen of the United States, residing at Queens. in the county of Queens and State of New York, have invented certain new and useful Improvements in Catsup-Caps, of which the following is a specification.

This invention relates particularly to the form of closures or caps for bottles or containers that have a comparatively narrow neck or top, and especially to those coir tainers that are screw threaded to receive a threaded closure.

The object of this invention is to provide a closure of this character that can be made from a blank or strip bent to a cylindrical shape. with one end closed by a disk; and

'in which hook portions on one end of the strip interlock with oblique edges on the other end of the strip. without the necessity of bending the said latter end of the strip to form engaging portions for the hooks.

A further object of this invention is to provide such an arrangement whereby the engaging portions will be located at the upper and lower portions of the body, and avoid unnecessary thicknesses of metal at the meeting or locking portions.

In the accompanying drawing showing one embodiment of my invention, Figure 1 shows the blank for the body member.

Fig. 2 shows the blank with one end portion bent to form books, also the intermediate edge being doubled back.

Fig. 3 is an edge view of the blank as shown in Fig. 2. I

Fig. at shows the meeting edges of the blank when first brought together.

Fig. 5 is a vertical section through the closure. 7

Fig. 6 is a longitudinal section enlarged on the line 66 of Fig. 5.

Fig. 7 is a horizontal fragmentary section enlarged on the line 7-7 of Fig. 4.

Fig. 8 is a fragmentary horizontal section enlarged on the line 8-8 of Fig. at.

In Fig. 1 is shown a blank 2 having at one end a dove-tail portion 3, that is formed by means of a notch at the upper and lower corner, to provide oblique edges 4 and 5 at these notches. At the opposite edge is a short tongue 6, beyond which at the top and bottom the corner portions 7 and 8 are bent on oblique lines to form hooks 9 and 10, as shown in Fig. 2. These books are directly Specification of Letters Patent.

opposite the oblique edges 4 and 5 at the other end of the blank. The tongue 6 is shown as doubled back on the blank 2, for the purpose of concealing the raw edge in the finished cap.

This strip as shown in Figs. 2 and 3, is bent to the form of a cylinder and the ends brought together, with the hook portions on the inner face. The hooks 9 and 10 are caused to engage the oblique edges 4 and 5 respectively, as indicated in Fig. 4;. This will cause a firm engagement and prevent separation of these end portions, both endwise and lateral.

The cap has one end closed by a disk 12, preferably by a kind of interlocking seam 13, formed by bending the edge of the cylinder inwardly in the form of an open channel, that engages a similar channel in the edge of the disk, see Fig. 6.

This joint with the disk preferably includes the hook 9 and the interlocking portion at the dove-tail end of the cylinder, as shown in Fig. 6. By this means the hook engagement is located at the end portion of the closure.

The other end of the closure preferably has the raw edge bent outwardly and up wardly to form a kind of bead, 14:, that includes the hook portion 10 and portion 5 of the dove-tail end of the blank, as shown in Fig. 6. By this means the lower hook is practically concealed in the bead of the closure. It will be further observed that the bent tongue portion 6 is located on the inner face and the raw edge is thereby concealed. The raw edge of the hook portions is further concealed by being located in' the bead at the botto'm of the closure, and in the seam at the top of the closure.

The closure is also given a helical corrugation, to form a screw thread 15, that will permit the closure to engage a screw threaded bottle neck.

It will be observed that a closure of this character is very simple of construction and assembly, it being necessary to merely bend back the hook portions, and the doubled edge at one end of the blank, the other end of the blank being adapted to engage therewith in the flat form, without being doubled or bent. It will be further noticed that the hook portion at the bottom is practically below the screw threaded part and does not interfere therewith.

\Vhat I claim is 1. A closure cap comprising a disk, and

a body formed of a metal strip bent into the form of a cylinder with the ends connected, the body having one of the ends provided with notches forming a dove-tail extension, the other end of the body having the upper and lower corners bent back on an oblique line to form hooks, which hooks engage the upper and lower corners of the dove-tail portion to connect the strip end portions.

7 2. A closure cap comprising a disk, and a body formed of a metal strip bent into the form of a cylinder with the ends connected, the body having one of the ends provided with notches forming a dove-tail extension, the other end of the body having the upper and lower corners bent back on an oblique line to form hooks, which hooks engage the upper and lower corners of the dove-tail portion to connect the strip end portions, said disk being interlocked with one end of thecylinder beyond the said connecting portions.

3. A closure cap comprising a disk, and a body formed of a metal strip bent into the form of a cylinder with the ends connected, the body having one of the ends provided with notches forming a dove-tail extension, the other end of the body having the upper and lower corners bent back on an oblique line to form hooks, which hooks engage the upper and lower corners of the dove-tail portion to connect the strip end portions, said disk being interlocked with one end of the cylinder beyond the said connecting portions, the other end of the cylinder being formed into a roll or head including the lower hook portion.

4:. A closure cap comprising an end disk, and a body formed of a metal strip bent into the form of a cylinder with the ends connected, the body having one of the ends provided with notches forming a dove-tail extension, the other end of the body having the upper and lower corners bent back on an oblique line to r'orm hooks, which hooks engage the upper and lower corners of the dove-tail portion to connect the strip end portions, said disk being interlocked with one end of the cylinder, the other end of the cylinder being formed into a roll or bead.

5. A closure cap comprising an end disk, and a body formed of a sheet metal strip bent into the form of a cylinder, one of the strip ends having at the upper and lower corners an edge that is inclined inwardly toward the middle of the strip, the other end of the strip having the corner portions bent back on oblique lines to form hook portions, which hook portions engage the said inclined edges'at the other end of the strip to connect the ends'of the cylinder.

6. A closure cap comprising an end disk, and a body formed of a sheet metal strip bent into the form of a cylinder, one of the strip ends having at the upper and lower corners an edge that is inclined in wardly toward the middle of the strip, the other end of the strip having the corner portions bent back on oblique lines to form hook portions, which hook portions engage the said inclined edges at the other end of the strip to connect the ends of the cylinder, said disk being interlocked with one end of the cylinder, the other end of the cylinder being formed into a roll or bead.

7. A. closure cap comprising an end disk, and a body formed of a sheet metal strip bent into the form of a cylinder with the ends lapping, one of the strip ends having at the upper and lower corners an edge that is inclined inwardly toward the middle of the strip, the other end of the strip having the corner portions bent back on oblique lines to form hook portions, which hook portions engage the said inclined edges at the other end of the stripdto connect the ends of the cylinder, said disk being interlocked with one end of the cylinder beyond the said connecting portions. the other end of the cylinder being formed into a roll or head including the lower hook portion.
